Since I would be placing the double 120mm rad at the top of the case, the first thing that has to come out is the 230mm fan. Unfortunately Cooler Master chose to use hex socket head screws to attach it. I did manage to find my hex key wrenches and got one to work, but this was a bit of a pain trying to remove these. The front 230mm fan is held in with standard Phillips head screws so there's no reason they couldn't have done the same for the top. It's almost as if they don't want you to remove it. Cooler Master's drive retention trays on the other hand are very easy to use and could even potentially be made hot swappable with a SATA backplane. The mounting pins are rubber isolated and really do help to quell vibration from the drives, particularly these noisy Raptors.

The push button drive locks are also one of the easiest optical drive retention mechanisms I've ever used. And the plastic riser card latches mean no fumbling with screws there either. The most time consuming part of installing hardware in the HAF is routing the cables, everything else is a snap. The 8-pin +12v power extension definitely came in handy as I would have had a tough time routing that cable without it. The main ATX cable came out a bit tight as well, but a minor change in the routing and all is well.
